3000 PSI WHD SERIES CYLINDER
FEATURES:
Configurable custom rod design
1-2 week lead-time
manufactured with Parker “Zero Leak” sealing technology
BENEFITS:
Additional outside diameter lip that prevents contaminates from entering the system by bypassing the OD of the wiper body.
Superior BTU rod seal increases the conformity of the seal to the rod. The second lip on the seal improves stability, limiting the rocking motion of the seal to reduce seepage
Buffer ring acts as a primary seal and pressure spike suppressor. The combination of rod seal and buffer ring results in an exceptionally dry rod for longer life.
Piston includes 2 wear rings and bronze filled PTFE seal designed for extension free, leak proof service
1045/1050 chrome plated, induction hardened, 100K rod is more resistant to damage to rod and seal
1026 DOM cylinder tube bores are skived and roller burnished to provide precision finishes for extended seal life

Hydraulic block actuator used by mould-makers to produce the motion required for ejection inside moulds.
This compact actuator is made up of three single-part components :
- the body, with roller burnishing of bore
- the hardened piston-rod
- guide ring
The advantage of such a design is that it minimises replacement requirements and prevents leakage.
We can supply a wide range of standard double acting block actuators with diameters from 16 to 200mm. Special strokes can be produced on demand. A key groove is also present as standard which prevents cylinder movements when the pressure get over 160 bars. The whole range is available with standard seals (Nitrile) or with Viton seals for temperatures from 100° to 150°C.
